ROLLER SIDE BEARING lECE RAILWAY-CARS.

To all whom t may concern Be it known that we, EDWIN and ERNEST A, LE `lnamcitizens of the United States, residingat Chicago, lllinois, have invented a certain new land useful lmgrovement in Roller Side Bearings for Railway-Cars, of which the following is a iull, clear, and exact description, such as will enable others skilled lin the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevational view partly in horizontal section of our improved roller side bearing for railway cars. Fig,v 2 a bottom plan view. Fig. 3 is a vertical cross Sectional View. Fig. Ll is an end View of the f main housing. Y

This invention relates to a new and useful improvement in roller Side bearings fori-ait way cars of the single roller type having centering means preferably'in-the forni of springs whose energies 'are normally exertedk to center said roller. rlhere is also a removable end memberor closure which, when In position, after the parts have been assem# bled, prevents the parts from becoming acf ycidentallydismantled. Y

llfhile we have Shown an inverted bearing designed especially to be attached to the body bolster of the car, it iS obvious that this bearing could be used on the vtruck bolster, in which event the roller would be presented upwardly and dirt exits would be provided at each end of the maincasting preferably in line with the surface of the track plate.

ylin the drawingsl indicates a casting having attaching lugs or earsv 2 extending from in the carriage 5, and l0 is the roller mounted on the axle within the carriage and, co-

operatingv with the track plate 3. The pe-` riphery of this roller extends beyond the plane of the edges of the: carriage. 'Y One of the end walls ll of the main casting is removably mounted in position being held in place by bolts '12. This vend wall when in position closes one end of the guiding grooves in the main casting and when removed permits the bearing to be dismantled for purposes of repair or renewal of the parts. The bearing members illustrated as an axle 9 may be either an independent axle keyed in the roller 10, or may be trunnions formed integrally with the roller.

ln the operation of assembling the parts of the device the removable end wall or closure ll is removed by disengaging the bolts '12, iln'dvwhen thus removedthe :carriage 5 can be readily introduced intothe casing positioned by passingthe'ends of its axle Y downward into the upwardly opening bearing seats provided in the carriage. the carriage has beenV thus mounted in the casing and the centering springs'arranged in place, the end wall ll is secured in place by the bolts l2, and thus serves tov prevent escape of the carriage from the casing, it being understood of course, that the carriage can be introduced into the casing only by an endwise entrance of the engaging flanges into the grooves Ll. It is apparent from the foregoing that there is provided a simple construction wherein the parts can be readily assembled or dismantled should circumstances revquire, and this by the simple eX-.

pedient of removing the en dwall 11'.
